Definitions

  • the present invention relates to a clip for sealingly connecting to a nipple, pipe stub or the like, a pipe, hose or the like, of a material with a tendency to cold flow, the clip including a constriction band, adapted to encircle the pipe, hose or the like and arranged to be tightened with a screw which is rotatably mounted in a holder.
  • the main object of the present invention consists of providing a clip that automatically maintains a sufficient sealing pressure, in spite of cold flow in the material of the pipe.
  • Another object of the invention consists in providing a clip which applies to the material of the pipe a sufficiently large, immediate deformation such that an immediate seal is achieved.
  • a still further object of the invention consists in providing a clip that achieves a balance between the continuous pressure that the pipe material can withstand and the pressure exerted by the constriction band, such that the cold flow is restricted.
  • the clip in accordance with the invention by the construction comprising a constriction band encircling the pipe and nipple to be connected, said band having overlapping ends adapted for displacement in relation to each other, a nut rigidly attached to one end of the band, a threaded spindle supporting said nut for travel thereon upon rotation of the spindle for displacing said one end of the band relative to the other and a resilient, U-shaped element accommodating the band and including legs straddling the band, the other end of the band being secured to one leg of said U-shaped element, said threaded spindle being mounted for rotation in the other leg of said U-shaped element, and disposed substantially in the central plane of the band.
  • FIG. 1 is a side view of one embodiment of a clip in accordance with the invention
  • FIG. 2 is a sectional view taken along line A--A in FIG. 1, and
  • FIG. 3 illustrates the clip of FIG. 1 mounted on a pipe and tightened to a predetermined pressure.
  • FIG. 1 A side view of an embodiment of a clip in accordance with the invention is shown in FIG. 1, the clip including a constriction band 1, adapted to encircle a pipe; hose or the like, not shown made from a material with a tendency to cold flow, e.g. plastics.
  • the constriction band 1 is disposed for being tensioned by a screw or threaded spindle 2, which is rotatably mounted in a holder 3.
  • One end of the band 1 is secured to a nut 4, adapted for travelling on the screw 2 when the screw is turned.
  • the other end of the band is, in the illustrated embodiment, attached to one leg of a U-shaped leaf spring 5, which is clamped in the holder 3 with the aid of its legs.
  • the U-shaped leaf spring 5 accommodates the band 1 and the legs of the spring 5 straddle the band.
  • the screw 2 is rotatably supported in the other leg of the U-shaped leaf spring 5 and the screw 2 extends substantially in the central plane of the
  • the end of the constriction band 1 attached to the leg of spring 5 extends through a slit 6 made in the other end of the band, in a manner illustrated in greater detail in FIG. 2.
  • FIGS. 1 and 2 the clip of FIGS. 1 and 2 is provided with an indication means 7, the function of which will be explained in detail in conjunction with FIG. 3.
  • the constriction band 1 is provided on its inner surface with ridges 8 along its edges, and the function of these will also be explained in conjunction with FIG. 3.
  • FIG. 3 the clip of FIG. 1 is illustrated as being positioned on a pipe 10, which is, in turn, pushed over the end of a metal nipple 9, not more closely.
  • the pipe 10 is made of plastic that cold flows when subjected to mechanical pressure.
  • the constriction band 1 has been tensioned around the pipe 10 by turning the screw 2 mounted in the holder 3.
  • the pipe 10 is compressed when the band 1 comes into contact with the exterior surface thereof. Since the U-shaped leaf spring 5 was prestressed in the ends of the holder 3, the spring 5 are first caused to be pressed closer together when the pressure of the band 1 against the pipe 10 exceeds the limit corresponding to the initial stress in the spring 5.
  • the ridges 8, already mentioned, on the inside of the band 1 are adapted such that the size of the surface engaging against the pipe 10 increases with continuing cold flow. There is thus obtained a high superficial pressure, the sealing pressure, directly on tightening the constriction band 1, and also a rapid decrease of the cold flow rate in the pipe material, because the superficial pressure decreases with increased contact surface. Due to the placement of the ridges 8 along the edges of the band 1, the pipe material between the ridges is compelled to flow a longer distance, which further reduces the cold flow rate.
  • the clip In the initial position, illustrated in FIG. 1, the clip is provided, as mentioned above, with an indication means 7, which is clamped between the inside of the holder 3 and the outside of the movable leg of the spring 5.
  • the indication means 7 In the illustrated embodiment of the indication means 7, it is provided with a protuberance 11, which has been slipped, in the initial position illustrated in FIG. 1, through a cutout, in the movable leg of the spring 5 through which the screw 2 is also passed.
  • the length of the protuberance 11 is selected such that the indication means 7 is freed from the clip when the movable leg of the spring 5 has moved a predetermined distance, at least corresponding to the calculated cold flow.
  • Dimensioning of the spring 5 in respect of spring bias and characteristic as well as the implementation of the constriction band 1 and nipple 9 coact such that, with time, the superficial pressure applied by the band 1 against the pipe 10 automatically approaches the pressure the pipe material can withstand.
  • the quality of the sealing joint is established upon release of the indication means and therefor is not affected by the skill of the operator performing the connection.
